To be honest Baron, I cannot claim to have a true tracking dog. I have a dog that finds deer, whether using wind or ground scent or whatever. I was ignorant to how to train a dog to track when I started out with my GWP and only had my experience with gundogs to fall back on as none of my mates at the time had trained tracking dogs either.
She has a fair bit of experience on deer as she is out with me almost every time I stalk and has been since she was about a year old. She is 9 this year.
She has probably gained that experience more through luck than my training.
